1 Claim. (Cl. 229-73) The invention relates to a dual-duty envelope, land more especially to an envelope possessed of independent pockets or compartments to be 'sealed from each other for retaining matter separated and concealed with respect to each other. f

The primary object of the invention is the provision of an envelope of this character, wherein its construction is an aid in coordinating and joining the efforts of two parties in corresponding Vwith another, especially during particular occasions, as for example, the doubling-up on gifts to charity and other instances and still be able ,to remember each other at' such times by written greetings or the like. Another object of the' invention is Vthe provision of an envelope of this character, wherein the sender may seal one pocket or compartment thereof and the receiver cannot inspect the contents but can seal the other after placing corref spondence within such envelope, refold'the latter and-mail it to a third party, and neither of the senders knows what the other has sent, `due to the arrangement of the flaps andA the'manner ofthe de 'signof the layout of the said envelope through the use thereof. v VA further object of the invention is the provision of an envelope of this character, wherein itslconstruction effects a dual purpose meeting a long required demand in correspondence trans'- mission under special occasions.

A still further object of the invention is the provision of an envelope of this character, which is extremely simple in construction, thoroughly reliable and efficient in operation, strong, neat in appearance, readily and easily handled,- con- 1 structed from a single unit, and inexpensive to manufacture and use.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as Y hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

Referring to the drawing in detail, A designates generally a single sheet of material, such as paper' orr the like from which blank the envelope constituting the present invention is made or constructed as hereinafter fully described.

The blank or sheet A is cut or otherwise formed to effect a substantially rectangular shaped main body I0 having at its longitudinal center a trans'- verse fold or crease line II dividing such blank body III into Vside-by-'side and edge-to-edge wall areas I2, I3, I4 and I5, respectively, the areas I2 and I4, and I3 and I5 are opposite to each other when the body Ill is further folded at its midway cross central portion on a fold or crease line II after folding on the fold or crease line I6 to effect twoindependent pockets or compartments denoted generally at B and C, respectively.

Following the fold or crease line II is an adhesive coating `I1 so that the wall areas I2, I3, I4 and I5 can be sealed together throughout this line II and the joining of the areas I2 and I4 and I3 and I5, respectively, in their companionship to each other, thus one pocket or compartment will not communicate with the other at this point f the nished envelope. At 'the longer outer edges of the wall areas -I2 land' I5, are sealing flaps IB and I9, respectively,

-each at the'- free marginal edging being provided with'an'adhesive-20, and these flaps I8 and If9 2| so that the pockets' or compartments Band C may be' closed and sealed by such flaps at the will ofthe user lof the envelope to confine and conceal the contents placed within such pockets or compartthe other.

` The wall areas I4 and I5 at their outer edges 'remoteffrom the crease line I6 between the areas "I2, I3, I4 vand I5 and unitary with the saidr areas I4 and I5 have an attaching wing 22 which is continuous with the said outer edges, while on one surface of this wing 22 is an adhesive 23 for sealed attachment to the outer end edges of the wall areas I2 and I3, the wing 22 being foldable along a crease line 24 following the outer end edges of the said areas I4 and I5. When the wing 22 is joined to the areas I2 and I3 the pockets or compartments B and C will be closed at the outer ends thereof confronting the said ment B is closed and sealed by the said wing 25;n and not by the ap I8 which is for a purposesvr hereinafter described.

For a second sending `of the envelope the body I0 of the latter will be reversed by folding following the -crease line II, which brings the pockets iB -and.
